Deepest sympathy to all the Concannon family. The true sign of Spring for us each year was when yard work began, and Jack would yell a loud and happy hello to us over the backyard fence. His passing is truly sad , but his memory will always be with me and bring a smile.

I was so saddened to hear of Jack's passing. He will always be in the hearts of the Maddocks family and remembered as a wonderful man and great neighbor. I will always smile when I think of his backyard fence greeting.."Hello neighbor!". Peace to you, Jack and, Mary and all the Concannon family.
